Can somebody help me draw this part out on solidworks??

This could - literally - be done in one single step...
Just draw half of it, then use the "Revolve" feature to make the part.

The major diameter is wrong.
A .75-20 UNEF thread should have a major diameter of: 0.7487" - 0.7405". .75" is too large, and out of the acceptable tolerance range.
Also uploaded a SW2019 file if anyone wants to see how to make the 3/4-20 thread without using the Thread tool (since that thread count/pitch is not an option).
